Abstract.
It is proposed the model for
the active multipanel composite reflecting surface of the main reflector of the
large millimeter radio telescope as large linear interval dynamic system with
parametric perturbations in the absence and presence of strong interpanel ties.
The problem of synthesis of optimal asymptotically stable robust regulator in
the class of centralized and decentralized structures to ensure stabilization
of the perturbed set of panels of the main reflector in a specified position is
discussed.
Key worlds: radio telescope, composite reflecting surface, large linear system,
interval models, centralized and decentralized control, robast
stabilization, asymptotic
stability.
